CowPots are the BETTER biodegradable pot.
USDA Specialty Crops Research Initiative funded a study that found Manure-based containers had nearly completely degraded (88 percent), while straw, wood fiber, soil wrap, peat, coir, and rice hull degraded 18-47 percent.*
Tender, young roots easily penetrate the sides and bottoms of CowPots, growing freely. This allows for air pruning and formation of root buds. Secondary root development throughout the pot grow into dense, healthy root systems recognized as critical to growing healthy plants
